IM PRCVEMENT IN LUBRIATQRS.

Specication forming part of Letters Patent. No. 154.418, dated August 25, 1874 application tiled June 2o, 1874.

To all whom 'it may'conoern:

Be it known that we, JOSEPH W. REED and MARTIN V. OSBORN, of Kalamazoo, in the county .of Kalamazoo and State of Michigan, have invented a new and useful Improvement in Lubricators, of which the following is a the line w w, showing more plainly the ports in the globe, and the mode of conveying steam to the coil in the reservoir.

Similar letters of reference indicate corresponding parts.

The case A of the lubricator has a glass lining, C, with an intermediate non-heat-conducting substance, D. It is also provided with a' screw-plug, F, in the top, and a strainer, E, like other lubricators heretofore patented. The oil may be warmed by admitting steam to the coil G, from the pipe H I below the globeA J. Said globe is bored transversely to reeeivethe plug K, which is formed on the shaft or stem. This plug is cast with a cavity, L, suiiciently large to contain oil to lubricate the steam-cylinder'once. This plug has two ports, onefor receiving the oil into the cavity L, marked m,

I and one for discharging it from the cavityL,

marked n. When the port m is open, as seen in Fig. 2, the port n is closed, and viceversa, as the plug is turned. 0n the shank O of this plug is an arm to which is attached arod, which extends to the cab, or within reach of the engineer, so that lhe may, without leaving the cab, lubricate the cylinders. P is an airpas sage through the globe, and Q is an air-passage through the plug. When the plug has been turned for lubricating, the oil descends into the cylinder by its own gravity as the plug is turned to open the ports, and bring the air-passages P and Q to register with each other to admit airto the cavity. Steam is discharged into the coil G from the point I.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination with the pipe H I, globe J, and hollow plug K, having supply and discharge orifices, Yas specified, of the airopeniugs P Q, as shown anddescribed, to operate as set forth.

2. The combination with the case A, of the concentric lining C, and intermediate nonheat-conducting substance, as shown and described.
